Apple on Monday announced an update to its mobile operating system to fix bugs, improve Siri and fingerprint-reading technology, and add new features such as CarPlay.

iOS 7.1 is the first major update since iOS 7, which was released last September. Users can now control how long Siri listens to them by holding down the home button for the desired time. iPhone 5s owners can set their phone to take “high dynamic range” photos. The new operating system also has an updated interface, with smaller, rounder icons.

Available for iPhone 5, the CarPlay phone integration system will allow drivers to make calls, get directions, or play music from their iPhone using the car’s built-in display. It can be controlled using voice or touch. CarPlay will be available in select 2014 vehicles, including some models from Mercedes-Benz, Volvo, and Ferrari.

Apple says the new update fixes an occasional Home screen crash bug for iPhone 5S users. Also for iPhone 5s: the Touch ID fingerprint technology is now more accurate. If you’re still holding onto an iPhone 4, this update should make it faster.
